Abstract
According to one embodiment, a multiple signal detect circuit (,) can include a detect node (,) and a reference node (,). The potential of the detect node (,) can be discharged (or charged) at a rate that depends upon the number of active input signals (M,to Mn). The potential of the reference node (,) can be discharged (or charged) at a reference rate. The reference rate can be greater than the rate at which the detect node (,) is discharged (or charged) when one input signal is activated, and less than the rate at which the detect node (,) is discharged (or charged) when two input signals are activated. A differential voltage between the detect node (,) and reference node (,) can be amplified by an amplifier (,).
